Display device and electronic equipment

Abstract

A display device includes: a display area having a resonator structure for resonating produced light; a protective film formed to cover the display area; a resin layer formed on the protective film; and a sealing layer attached by the resin layer, wherein the protective film includes a single silicon nitride layer, and has a refractive index between 1.65 and 1.75 at a wavelength of nm.

1 . A display device comprising:
 a display area having a resonator structure for resonating produced light;   a protective film formed to cover the display area;   a resin layer formed on the protective film; and   a sealing layer attached by the resin layer, wherein   the protective film includes a single silicon nitride layer, and has a refractive index between 1.65 and 1.75 at a wavelength of 450 nm.   
   
   
       2 . The display device of  claim 1 , wherein
 the internal stress of the protective film is nearly zero.   
   
   
       3 . The display device of  claim 1 , wherein
 the protective film is between 100 nm and 1 μm in thickness.   
   
   
       4 . The display device of  claim 1 , wherein
 the display area is covered by the protective film so as not to be exposed to the atmosphere.   
   
   
       5 . The display device of  claim 1 , wherein
 the display area has an organic layer including a light-emitting layer between first and second electrodes, and has organic light-emitting elements adapted to extract light produced by the light-emitting layer from the side of the second electrode.   
   
   
       6 . The display device of  claim 1 , wherein
 the difference in refractive index between the protective film and resin layer is 0.3 or less at a wavelength of 450 nm.   
   
   
       7 . Electronic equipment having a display device in its main body enclosure, the display device comprising:
 a display area having a resonator structure for resonating produced light;   a protective film formed to cover the display area;   a resin layer formed on the protective film; and   a sealing layer attached by the resin layer, wherein   the protective film includes a single silicon nitride layer, and has a refractive index between 1.65 and 1.75 at a wavelength of 450 nm.
